3 Claims.

The invention relates to improvements in window stays or devices for holding swinging closures, such as storm windows and screens, in adjusted positions.

The primary object of the invention is to provide a window stay or adjuster having means for convenient disconnection from the storm window or screen, or from the window frame and to provide for this purpose a releasable latching means of extreme simplicity and durability and one which may be readily manipulated without the use of any tools. Another object is to provide a window stay of this character which is inexpensive to manufacture and in which all of the necessary swinging or pivotal connections are arranged to prevent such looseness as would cause the very objectional rattling which is found so often in certain other stays. Still a further object is to provide a releasable latching means for attachin the stay to window or frame which is so constructed that it will not be liable to disconnection or dislocation due to vibration or like causes.

These and other more detailed and specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawing, in which Fig. 1 is a side elevation of the stay showing the same arranged upon a window frame and screen or storm sash and with the latter swung outward some distance from the frame, only fragments of the frame and sash being illustrated.

Fig. 2 is a plan view of the stay alone.

Fig. 3 is an enlarged, fragmentary sectional view taken along the line 3-3- in Fig. 1.

Fig. 4 is a fragmentary side elevation of one end of the window stay and adjacent attaching bracket, showing the latch member swung to a position for releasing the stay from said bracket.

This application is a division of my copending application for Window stay, Serial No. 366,355 filed November 20, 1940.

Referring now more particularly and by reference characters to the drawing, a section of a swinging closure such as a storm window or screen is indicated at A and a section of the window frame at B, said window or screen being of the conventional form adapted to swing outward at one, usually lower, edge away from the window frame as clearly indicated.

My improved stay, designated generally at C, is adapted to hold the window, or screen, in adjusted positions relative to the window frame and for this purpose the stay is connected at its ends to both members A and B. Two stays are usually employed, one at each side of the frame, but since the minor changes required for right or left mounting are so apparent the description of one stay will be suflicient herein.

The stay comprises an articulated foldable brace made up of inner and outer arms or arm members 5 and 6 pivotally connected at meeting ends by a bolt I. The end of the inner arm 5 is pivoted by a rivet or similar means 8 to a bracket 9 which may be secured by screws I0 to the frame A, said bracket being offset to cause its center portion II to stand outwardly from the adjacent surface of the frame to provide clearance for the rivet head. A friction washer I2 of Bakelite, fiber, hard rubber or similar material is placed between the arm end and bracket so that the arm will not swing too freely on rivet 8 and looseness and rattling will be prevented at this point.

The outer arm 6 carries a rigidly mounted and laterally extending pivot pin I3 near its outer extremity and this pin is adapted to be pivotally received in the apertured ear Id of a bracket I5 which is secured by screws I6 to the storm window or screen. A swinging latch member I? is pivotally mounted by a rivet or similar fastener I8 to the same side of the outer arm 6 as that from which the pin I3 projects, and inwardly with respect to said pin. The intended outer end I9 of the latch member I! is ofiset to stand away from this side of the arm 6 by a distance just nicely to clear the bracket ear I4 when this ear is in engagement with the pivot pin I3. See Fig. 3. This end I9 of the latch member is rounded at its extremity 20 on a radius centered at the rivet I8 and is adapted to swingably enter a notch or groove 2| cut in the adjacent side of the pin I3 in which position the latch member will obviously prevent the pin from being withdrawn from the bracket ear I4, but will interfere in no way with swinging movement of the arm 6 with respect to the bracket.

When thus engaged with the notch in pivot pin I3 the latch member I! is extended substantially longitudinally along the arm 6 and its end opposite the pin is folded or creased to provide an outstanding operating or finger portion 23 by which the latch member may be readily swung about the pivot afforded by rivet I8. The arm 6 has a boss or knob 24 pressed outward in position to be engaged or straddled by the parallel folded margins or raw edges 25 formed by the folding of this end of the latch member, and accidental swinging of the member upwardly, swinging in parallel planes about their center pivot connection I, and their end conscreen is swung inward and outward with respect to the window frame. When a storm window is to be replaced with a screen the latch member I! is swung aside to the position shown in Fig. 4 whereupon the pin I3 may be with nections 8 and I3, as the storm window or and scope of the appended claims. Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent is:

l. A window stay for releasable connection to a window element, comprising an arm, a pin extended therefrom, a bracket member secured to the window element and having an ear with an opening therein to pivotally receive the pin with the adjacent end of the arm flatly engaged with the bracket ear, a latch member pivoted on the arm in fiat contact therewith and hav- 7 'ing an end offset therefrom to overlie and flatly drawn from the ear I4 by slightly springing the outwardly arched operating portion, and a boss punched from the arm for engagement with the outer arm 6, and the pin may then be intro: duced into a similar ear in a bracket affixed to the screen, or the stay may be simply folded against the window frame if screen adjustment is not desired.

The meeting ends of the arms 5 and 6 overlap each other and are apertured to pass the bolt '1 which has a head 21 and a nut 28 by which it may be drawn tight. Hard rubber, fibre or Bakelite washers 29 are placed between the bolt head 21 and adjacent arm, and between the arms, and by drawing up the nut 28 sufficient tension or resistance may be provided at this center joint so that, when extended as in Fig. 1, the stay will positively support the window or screen A in openedposition,

The outer arm 6 has a flange 30 turned from its upper or outer edge and a finger 3| extends from the end of the innerarm 6 in position to engage the end 32 of this flange before the arms reach a straight or dead center position from which they might fold in a downward direction.

Obviously the stay may be reversed, where conditions will permit, to place the bracket 9 on the storm window or screen and the bracket I5 on the window frame if so desired.

It is understood that suitable modifications may be made in the structure as disclosed,'provided such modifications comewithin the spirit engage the opposite side of the apertured ear of the bracket member and hold the same in engagement with the pin, the opposite end of the latch member being creased to provide an 2. A window stay, comprising an, arm, a pin extended from the arm at right angles to one side thereof, a bracket member having an apertured ear adapted to pivotally receive the pin and rest flatly against the said side of the arm, the said pin having a groove in one side, and a latch member pivotally mounted on the arm and adapted at one end to overlie and flatly engage the other side of the bracket ear and releasably engage the groove in the pin.

3. A window stay, comprising an arm, a pin extended from the arm at right angles to one side thereof, a bracket member having an apertured ear adapted to pivotally receive the pin and rest flatly against the said side of the arm, the said pin having a groove in one side, a latchmember pivotally mounted on the arm and having one end ofiset to stand outwardly from the arm to overlie the bracket ear .and flatly engage the opposite side thereof, and said offset end being longitudinally crimped to efiect a centering action in the groove in the pin.
